Abstract
Portable projection screen assemblies include: (a) a roller housing holding a roller with a flexible projection screen; (b) at least one substantially laterally extending screen support arm attached to the roller housing, the at least one screen support arm being configured to hold an outer edge portion of the flexible projection screen when the projection screen is in a laterally extended configuration; and (c) an outer housing case having an interior cavity sized and configured to hold the roller housing therein in a storage configuration. The roller housing is hingeably or releasably attached to the housing case and resides substantially vertically above the outer case in an operative position, whereby the outer housing case defines a support base adapted to reside on a support surface.
